My improved cop winding wachine, as herein shown and described, isconstructed and arranged to produce a cop of the well known open,self-binding wind. The thread is wound upon a quill of card-board or thelike; this quill is slipped endwise onto a spindle 1 and the leading endof the thread as is fastened theretoI When the machine is started thespindle and quill rotate together and the thread 00, directed by thereciprocating. thread guide 2, is wound onto the quill to build up thecop. The thread guide and the-spindle are so connected that the threadguide reciprocates rapidly along the face of and provis on is made toadjust the speed relation of the two parts so that each succeedingspiral of thread,'in a given directlon will be laid alongside thepreviously laid spiral in the same direction and will blnd down allspirals laid in the opposite direction. All this is old and well known,

constituting what is known as the Fiji wind and need not be elaborated.

The spindle 1 is journaled in a bearing 3 and carries a fast, slightlyconical, pulley 4 and a loose pulley 5 with both of which a main drivingbelt 6 cooperates, said belt being driven from any suitable source ofpower.

v The thread guide eye 2 is mounted on a tang 7 rigidly connected to andcarried by a tubular carriage 8 slidably mounted upon a thread guiderail 9. The rail 9 is fastened at its ends to arms 10 forming part of ahousing 11 formed with hubs 12 and 13 rotatably supported by a fixedarbor 14. Within the housing 11 the arbor 14: has, loosely mountedthereon, a sleeve 15 .to which is fastened a cam 16 carrying a hub gear17,

said sleeve being heldagainst endwise move-' ment on the arbor by thehub 13 and a collar' 18 that is fastened to the' arbor by a screw 19.The arbor 14 is supported by an upright frame 20 made with a hollow hub21 within which one end of said arbor is fixed so that it cannot rotate,by means of a screw 22 (Fig. 4). The cam 16 is made with a groove 23into which projects a stud 24 depending from the lower side of threadguide carriage 8, said stud carrying an anti-friction roll 25.

The gear 17 is driven by a pinion 26 fast to one end of a shaft 27 whichalso carries a slightly conical pulley 28 connected by a belt 29 withthe pulley 4, the small end of each of said pulleys being opposed to thelarge end of the other pulley. The belt 29 is engaged by a belt-guidingyoke 30 which is slidably mounted upon a stud 31 projecting from theframe 20. This guide 30. is made with an ear formed with a tapped holethrough which a screw 32 extends, said screw being rotatably mounted ina bearing provided on the frame 20 and provided with a handle 33 bymeans ofwhich it may be rotated to shift guide 30 on the stud 31 toexactly adjust belt 29 according to the exact speed relation desiredbetween cam 16 and spindle 1. That is, by adjusting the guide along thestud 31 by means of screw 32 the speed of rotation of cam 16 withrelation to the speed of rotation of spindle 1 may be increased ordiminished to cause the thread guide 2 to lay the convolutions on thecop side by side, so that the cop, although formed of open spirals maybe solid.

The shaft 27 is rotatably supported at one end of an arm 34 whose otherend is made with two hubs 35 and 36, the former being split and clampedto the hub 21 of frame 20 by means'of a screw 37 (Fig. 4). A collar 38is arranged between the two hubs 35 and 36 and fastened to .the hub 21by a screw 22 and serves to hold arm 34 against sidewise displacementwhile being adjusted.

At its outer free end the arbor 14 is made with an angular Vertical hole38, within which is slidably mounted a pawl 39 consisting of a bar of:metal provided for convenience with a handle 40, the lower end of thepawl 39 cobperating with a stop 41 provided on the -housing 11. The pawl39 and stop 41 are arranged and constructed so as to permit the housing11 to rotate freely in a direction to permit the thread guide, which,

' is carried by the housing, to shift away from spindle 1, but toimmediately check and prevent any movement of the houslng 11 in theopposite direction. In other words the pawl I 39 and stop 41 provide aclutch which normally prevents any rotary movement of the housing in onedlrection and at the same time leaves it entirely free to swing in theopposite direction.

One side of the cylindrical portion of housing 11 consists of aseparable section or cover 42 fastened-to the main portion by a screw 43and on this cover 42 is secured, by means of a screw 44 an angularlyadjustable counterbalance weight 45 consisting of a block of metalformed with a slot-46 through which the screw 44 extends. This weight 45together with the weight of the cover 42 and those portions of thehousing 11 at one side of the arbor 14, slightly overbalances the weightof the portions of the housing 11 and associated parts, at the oppositeside of the-arbor and of the parts carried thereby, with the result thatthe thread guide is yieldingly urged toward the spindle, but it is to beborne in mind that the clutch 3941 normally prevents movement. of thethread guide in that direction so that during the winding operationthere is practically no continued pressure of the thread guide againstthe growing cop. This is due to the automatic take up action of theclutch 3941 together with the fact that whenever the growing and rapidlyrotating cop comes into contact with the thread guide the minuteirregularities of the cop cause the thread guide to be kicked away fromvthe cop slightly, whereupon it is caught and cop again touches thethread guide and the thread guide is again kicked back slightly andcaught. It will thus be seen that the thread guide only engages thegrowing cop intermittently and each time is soon thrown out of contacttherewith by the slightest irregularity in the cop. This results invmore width as the thickness of the tang so that the latter is guided andsupported and held against vibration or chattering. The cam 16, rapidlyreciprocates the thread guide 2 lengthwise of the spindle 1 and at eachend of its stroke the direction of movement of said thread guide isabruptly reversed so that if the thread guide and its carriage includedany considerable mass of metal in their construction the shock of thisabrupt reversal of movement would be injurious. For this reason I makethe thread guide and tang from light and thin metal and the carriage 8from a light, thin piece of tubing so that said parts acquire acorrespondingly small held by the clutch 3941 until the growing amountof momentum during their movements. Owing to the lightness of theconstruction of the thread guide I find it desirable to provide a threadguide supporting rail 50 provided at its ends with legs 51 ports thethread guide eye against any pressure against the cop and pull of thethread or yarn during the winding operation.

The housing 11 is made, upon its under side, with a lug 52 carrying anadjustable secured to the casting 47. This rail sup-' stop screw 53which cotiperates with the rear side of a lug 54 'cast on the frame 20to limit the swinging movement of housing 11 in one direction. In orderto limit the swinging movement ofthe housing in the opposlte directionsaid housing is made with a lug 55 cooperating with the opposite side oflug 54.

wise movement. From the disks,'the thread passes under a drop wire 59and upwardly over rail 50 to the thread guide eye and cop.

Slidably mounted upon the spindle 56 is a sleeve 60 which is exteriorlythreaded to receive upon it an adjustable nut 61 between which and disk58 is arranged a spiral spring 62 which yieldingly presses against aloose sleeve 62 which in turn abuts upon the disk 58 and presses itagainst the thread or yarn as it passes around spindle 56 and betweenthe disks 57 and 58, the initial pressure of the spring62 against disk58', and

therefore the initlal tension on the yarn or thread being determined bythe adjusted position of the nut 61 on sleeve 60 and the consequentspring pressure. During the opera- 1 tion of building a cop, thecop, ofcourse, grows'in diameter, with the result that the yarn or thread isdrawn from the supply at a contlnually increasing rate ofspeed whichincreases the tensionon the thread or yarn in exact proportion to theincrease inspeed.

and in order to counteract this and maintain the proper tension, I haveherein provided for automatically relaxing the tension producing deviceor devices as the speed of movement of the thread or yarn increasesduring the growth of the cop. To accomplish this the sleeve60 is made atone end with an arm 63 pivotally connected with a small sleeve 64slidably mounted upon a cam bar 65. This cam bar 65 is pivoted at 66 toa slide 67 and its opposite end extends loosely through a square sleeve68 resting upon the top of slide 67. Sleeve 68 is pivotally connected toa square nut 69 mounted upon a screw 70 rotatably supported at its endsby slide 67 and held against endwise movement thereon by a collar 71 andthumb piece 72.

At its forward end the slide 67 rests upon an arm 73 forming 'part ofthe frame of the machine while the rear end-of said slide is supportedby the lug 55 to which it is pivotally connected by a screw 74. Thus itwill be clear that the slide 67 is shifted bodily on arm 73 whenever thehousing is swung on arbor 14 and that the direction of this slidingmovement of said slide is crosswise of the axls of spindle 56. By meansof the screw 70 the cam bar is set in a diagonal position relatively tothe spindle 56 so that amount which it is distorted from its nor-' -malspiral. This property is taken advantage of in the ordinary springbalance scales, in which the graduated plate indicating the weight isequally spaced and the spring correspondingly distorted by the weight. Itake advantage of this by employing a straight cam bar which when set atthe proper angle, for every inch of radial growth of a cop andconsequent increased speed of the thread, will exactly compensate bypermitting the spring to correspondingly expand and thus decrease thetensional drag on the thread in exact proportion-to the increase causedby the increase in speed. I have shown adjusting means to vary the angleof the straight cam bar, since it is not always desired'to keep thetension uniform, but it may be desired to gradually increase or decreasethe tension as the cop builds.

I have shown in the drawings and in detail in Fig. 1 the preferred formof tension member, in which one member (57) is supported and securedupon the spindle by a yoke 57 and has an axial perforation 57 while theother member (58) has a hub 58 which passes through the perforationleaving anannular space. The object ofthis is to provide a wearingsurface to protect the spindle from the cutting effect of the rap- .idlymoving thread and a free outlet for the lint, etc., which is constantlybeing stripped from the thread by its engagement with the tension disks.The tension device above described is not claimed in this application,but will form the subject of a divisional application.

I have also provided a stop motion, which automatically stops themachine in case of breakage of the thread during the winding process.The drop wire 59 is pivoted at 75 to the arm 73 and its hub portion isformed with a cam 76 coiiperating with a roll 77 provided upon one armof a lever 78 piv-- oted at 7 9 to the frame of the machine' The otherarm of lever 78 carries a pin 80 normally in engagement with a pin 81carried by an arm 82 fast on a rock shaft 83. This rock shaft 83 hasfixed to it another arm 84 that is pivotally connected with one end ofalink 85 whose opposite end is pivotally connected with a belt shipper86. The belt shipper 86 which is provided with a yoke 87 straddling thebelt 6 is pivoted at 88 to an arm 89 cast integral with bearing 3 andhas connected to it one end of a spring 90 whose opposite end isconnected with said arm. The spring 90 tends constantly to shift beltshipper 86 into position to place the belt 6 on loose pulley 5 but isnormally prevented from doing so by the engagement of pins 80 and 81.

When the yarn 'or thread that is being wound onto the cop breaks thedrop wire 59, being no longer supported thereby, falls, and its cam 76acts to swing lever 78 in a direction to disengage the pin 80 from thepin 81 whereupon the spring 90 shifts belt shipper 86 toward the right(Fig. 1), shifting the belt 6 onto the loose pulley 5 and stopping themachine. In order to provide for manually starting the machine and resetting the break stop motion mechanism, the rock shaft 83 is providedwith a handle 91.

' Herein I have also provided means for automatically stopping themachine when the cop that is being made reaches a predetermined size.This means comprises a screw 92 rotatably mounted on slide 67 and heldagainst endwise movement thereon by collars 93 and 94 and provided witha nut 95 adjustably mounted on said screw. By rotating the nut 95 it maybe set so that when the cop-reaches the desired size said nut engagesthe lever 78 and thereby disengages the pins 80 and 81 so as to stop themachine.

Cops of the kind that my improved Ina-- chine is designed to make areproduced either cylindrical or conical in form andherein 1 have providedfor producing copsof either form. To this end the frame 20 is made witha seat 96 upon its upper surface for the bearing3, said seat being madewith a series of tapped screw holes 97 and 98,-and the bearing 3 is madewith cars 99 which are fastened to the seat 96 by screws 100 engagingthe proper screw holes. When the bearing 3 is fastened in place on theseat 96 by inserting the Screws in the holes 97 as shown in thedrawings, the axis of the spindle 1 is parallel with the path ofmovement of thread guide 2 and a cylindrical cop will be produced. Whenit is desired to produce a conical cop the screws 100 are removed fromholes 97 and transferred to one or the other of thethree sets ofholes 98according to the degree of conicity desired, it being clear that theholes 98 are positioned so that when used to fasten bearing 3 to seat 96the axis of the spindle 1 will be oblique with relation to the path ofmovement of the thread guide. Several sets of holes 98 are provided sothat cops of about a center 00 and the link 85 is connected shifter andthe belt shifter functions prop erly without any necessity foradjustment or attention in whatever position the spindle bearing may be.

The operation is as follows: The thread to be wound having been threadedthrough the tension disks, 57, 58, under the drop wire 59 and over theguidesupport 50 to the thread guide eye and secured to the quill,

the machine is started by lifting the handle 91, thus, through arm 84and link 85, shifting the belt shipper 87 to shift the driving belt fromthe loose pulley 5 to the outer edge of the cone pulley 4. This movementis against the effort of spring 90 which constantly tends to shift theClI'iViIlo; belt to the loose pulley. The lifting of handle 91 alsomoves arm 82 and causes the engagement of pins 80, 81 (Fig. 1). Thisengageable nut 95, mounted upon'a' slide or carriage 67. The growth ofthe cop gradually shifts the housing 11 and draws the carriage inwarduntil the nut 95 engages arm 78 and lifts it, thus disengaging the pins80,

This shifting is also automati- 81, and permitting spring 90 to operatethe shift and thus stop the machine. Slight irregularities in the cop orthe most recently laid coils, as the cop Irotates, continually strikethe thread guide and force it backward. If this efiect were continuousand uncontrolled the result would be that the thread guide and itssupports would be continuously vibrated and the thread guide wouldnecessarily require to be strongly built to withstand such usage, whilethe continual strike and repulse action would be damaging to the cop.This is prevented by the pawl 39' cooperating with a stop 41. The pawl39 is shown as operating by gravity and, as the stop 41 is shifted bythe cop, through the thread guide' 2 carried by the housing 11 to whichthe stop 41 is secured, the pawl instantly drops and continually.maintains its engagementwith the stop and securely locks the partsagainst any return swing. The positioning of the spindle land itsbearing 3 for cylindrical or conical cops ,does not disturb in any waythe connection by which the hreak-and-size-stop' motionsare madeeffective to shift the driving belt,

the connection being universally jointed and so positioned 1n themachine with reference to the point about which the spindle is moved toits various positions, that practically no derangement of the partsoccurs and no adjustment is necessary.
